Property and introduction of converter

CGZ-01, CGZ-02A Intelligent converter

Features:
■Programmed low frequency rectangular wave excitation, higher flow measurement stability, lower power loss.

■16 digital built-in micro-processor, higher data processing speed, higher accuracy

■all-digital data processing, stronger anti-disturbance, reliable measurement ,flow measurement rang rate: 1500:1

■super-low EM1stwich power, large rang of power voltage, good performance of anti-EMC

■menu operation in Chinese, high visibility backlight LCD display, easy operating

■double direction flow measurement function, positive and reverse direction flow display, double direction electric current and frequency output

■inner 3 accumulators display positive accumulation, reverse accumulation and balance of accumulation

■RS485 digital communication signal output

■Fluid conductivity measurement function, judge if transducer is empty

■Data setting agilely, being suitable for different types of electromagnetic flow transducer

■Have self-check and self-diagnose function

■When power-off, EEPROM saves the setting value and accumulative value for over ten years

■Utilizing LS semi-conductor chip and SMT technology, good reliable circuit

■Separated and integrated structure

Technical data
Operation condition:

   Relative humidity: 5%～100%
   Power supply: 85V-265V AC; 45～63 Hz; 24V DC
   Power: <20 W

   Accuracy: + 0.2% of measured value
   Repeatable error: 0.1% of measured value

   Output current: dual-direction and two lines whole isolation, 0~10 mA or 4~20mA
   Load resistance: 0~1.5kΩ for 0~10mA; 0~750Ω for 4~20 mA
   Basic error: add +1μA on base of measured basic error
   Frequency and pulse output:
   Frequency output: frequency output superior limit value set between 1~5000Hz. Collector of conductor with photo insulation device output open. When out power supply is less than 35 V, max. current of collector is 250mA at conduction.
   Pulse output: pulse output superior likit value arrives at 5000cp/s. Pulse is 0.0001~10m?/cp. When collector of conductor with photo insulation device output open, pulse width is 10ms~2.5s. When out power is less than 35V, max. current of collector of conductor is 250 mA at conduction.
   Warning output: collector of conductor with photo insulation device output warning single open. When out power supply is less than 35 V, max. current of collector is 250 mA at conduction.
   Communication output: RS485 communication output (special order)
   Insulation: insulation voltage among the analogue output, (pulse) frequency output, warning output and the earth is not less than 500V.
